Image disappear in Develop Module after Deletion of Other Images

Hi,

In Lightroom 5 and 5.2, when using the X key, then Delete Rejected Photos, the central display box no longer displays an image. If I switch back to Library mode an image will appear but if I go back to the Develop module, again it's a blank screen! Is this a known issue? If not, how do I report this directly to Adobe?

Thanks

John
